Simple test

Ensure your device works with this simple test.

import displayio
import board
from uhistogram import Histogram

display = board.DISPLAY

data = [5, 4, 3, 2, 7, 5, 3, 3, 3, 3, 2, 9, 7, 6]
my_box = Histogram(data, x=50, y=50, width=100, height=100)

my_box.print_data()

Text Example

A more advance example to illustrate how to add text to the histogram

examples/uhistogram_text_example.py

import displayio
import board
import terminalio
from adafruit_display_text import bitmap_label
from uhistogram import Histogram

display = board.DISPLAY

data = [5, 4, 3, 2, 7, 5, 3, 3, 3, 3, 2, 9, 7, 6]
my_box = Histogram(data, x=50, y=50, width=100, height=100)
my_box.draw()
my_group = displayio.Group()
my_group.append(my_box)

for i in range(my_box._numbins):
    text_area = bitmap_label.Label(terminalio.FONT, text=str(int(my_box.bin_data[i])))
    text_area.x = (
        50 + my_box._xstart + int(i * 1 * my_box._graphx) + my_box._graphx // 2
    )
    text_area.y = 160
    my_group.append(text_area)

display.show(my_group)
while True:
    pass
